Application-ledAugvust 25, 191,6. .SeralNof1165804 To yall `wwwmlt mag/concern Beit fknown that 1I, AUG .trs'rINn` B. RE- PETTO, a citizen `of :the United -States, `and a residentof Margate 'City, inthe county `of Atlantic andState-of New Jersey, have invented a certainnew and useful Saw-Set, of whichthe *following is a specification.

The principal Iobjects of ithe lpresent invention are too-provide a comparatively linexpensive, simple, -reliable and `compact saw-*setlwhich canA bev used even by unskilled persons for-rapidly and accurately setting the teeth ota saw;`to provide simple adjustments =for-the saw-'set whereby it can be readily `adapted ffonusein connection with saws having teeth of different pitch and wherebylit can` be adapted to givethe saw teethany-requi-red set `or inclination tothe generalplane `oli-the saw. @therV objects will' appear `from the `following description.

Stated-ingeneral terms'theinvention consists of alsaw `set .comprising the combr nation of 4 concentrically `pivoted "pairs of spring-opened clamping-and setting tongs having their shanks 1in substantially' the same plane, andv 'of which the clamping tongs arefprovided `with saw tholding `lips and the setting tongs are provided with sawsets operatively arra-ngedfin respect to -the lips, whereby ythe shanks oi' thesetting tongs constitute handles and operatebetween them the shanksfofA` the clamping tongs.

rllhev invention 4further' comprises the Y provisiongot adjustable abutments between the Shanks of the Arespective tongs `for fixing the degree of inclination imparted to the saw teeth, andl 'the Ainvention =furth`er comprises the improvements to be presently described andfnally-claimed.

The accompanying drawings illustrate an embodiment of the invention, anjd `in them- Figure-i1 is a perspective view.

Fig. 2, isa diagrammatic `view .showing the pivotpin Flg. 13,-is-1'a ffrontf-view with parts broken away showing diagrammatically a portion of a sawin `positionin the tool, an'dvshowf` ing the saw sets adjusted to the saw teeth.

Fig. 4, is an end view showing the tongs in open position, and

Fi 5, is a side view, partly in section, showing the tongs in closed position on a saw and the saw sets in open position about to begin to do their work.

In the drawings 1 are a pair of clamping tongs and 2 are a pair of setting tongs.

These pairsottongs areconcentrically pivoted `as'lby 4means of the pivot pin 3. The Shanks 4 and 5 of these tongs are arranged insubstantially the same plane. The clamping .tongs 1 are provided with saw holding lips 6 between which and the pivot pin 3 a portion is cutaway as `at 7 to adord clearance forithe teeth of a saw. The setting tongs2areprovided with saw `sets 8 operativelyarranged in respecttothelips 6 that is,lthey vare arranged between the lips and thewpin 3 andin a space provided `in the tongs 11. I A portion `9 of the pin is threaded, `and `poi-tions ofitfare not threaded. @ne of the setting tong members 2 is tapped and arranged on this threaded vportion 9 andthe rest yof the tong members are a1'- ranged onunthreaded portions of the pin, sothat by: turning the `pin the tong members 2, ormore accurately the saw sets `8, can be moved toward and away romeach other to adjust the setto saws having teeth of difierent pitch. `1Ois a lock nut for holding the tongs 2 in .adj usted position. The shanks 4 constitutehandles that may be pressed toward eachother in the handof the operator and when they `are pressed `toward each other they pressv the shanks 5 between them and so cause the saw sets to move toward each other. .11 are adjustable abutments, shown `as screws,.and they are interposed between the Shanks 4 and 5. By adjusting these abutments the relative i `movement of the Vsaw `sets 8 can be changed so as to give the requiredinclination or set to the saw teeth. 12 is .a spring, shown as interposed between the-Shanks 5, and it tends to hold the tongs 1 and lips 6 normally in open position.v k13 vare spring extensions on the Shanks 5 and ythey tend tonormallyhold the shanks `4 `in open position, but they yield to permit of the described operation ofthe shanks 4 on the shanks 5 through the instrumentality of the adjustableabutments 11. 14 are stops that may` be. provided `on the tongs 5 and they serve to limit the possible range ofinward movement of all the shanks. 15 is a stop for limiting the' outward movement of the Shanks 5. Each element of the tongs 1 is provided with arms 16 and 17 extending from its lips 6 to the pivot pin and spaced apart to accommodate the sets 8. The arm 17 is prolonged past the pivot pin and orf-set inward as at 18 so as to bring the Shanks 5 in the same general plane as the Shanks 4. Whatever movement may be given to one of the members of the tongs 1 by the screw thread on the pin 3 is insutlicient to destroy the substantial alinement of the shanks of all of the tongs in substantially the same plane.

In use the saw sets 8 are spaced 'to ac-l oommodatethemto the pitch of the teeth of the saw by means of the threaded engagement of one of the tong elements 2 with the threaded portion 9 of the pin and are f secured against accidental displacement by ting the teeth, see Fig. 5. The tool is moved 18, acting to turn the arms 5, without yielding appreciably, but the spring 12, yields and the arms 4 and 5, maintain substantially the same relative position and the parts 8, come up to their` work without actually setalong the saw and operated in the manner described so setting additional teeth.

It will be obvious to those skilled in the art that modifications may be made in def .z tails of construction and arrangement without departing from the spirit of the invention so that the latter is not limited as to those matters or in any way other than the prior state of the art and the appended claims may require.

What I claim is: 1. A saw-set comprising the combination of concentrically pivoted pairs of spring- 4 opened clamping and setting tongs having their shanks in substantially the same plane and of which the clamping tongs are provided with saw holding lips and the setting tongsare provided with saw sets operatively arranged in respect to the lips, whereby the u shanks of the setting tongs constitute handles and operate between them the shanks of the clamping tongs, substantially as described. i

2. A saw-set comprising the combination of concentrically vpivoted pairs of springopened clampingand setting tongs having Copies of this patent may be obtained for their shanks in substantially the same'plane f' and 'of which the clamping tongs are provided with saw-holdinglips and the setting tongs are provided with saw sets operatively arrangedin respect to the lips, and adjustable abutments between the shanks of the respective pairs of tongs, whereby the shanks of the, setting. tongs constitute handles and operate between them the shanks of the clamping tongs, substantially as described.

3. A saw-setcomprising the combination oi concentrically pivoted pairs of springopened clamping and setting tongs `having their shanks insubstantially the same plane and of whichthe clamping tongs are provided with saw holding lips 'and the setting tongs are provided with saw sets operatively arranged in respect' to the lips, adjustable abutments between the shanks of the respective pairs of tongs, and-stops `between the shanks of the clamping tongs, whereby the shanks of the setting tongs constitute handles and operate between them the shanks of the clamping tongs,substantially as described.

4, A saw-set comprising theJ combination of pairs of spring-openedclamping and setting tongs having their-shanks in substantially the same plane and of which the clamping tongs are provided with saw holding lips and the setting tongs are provided with saw sets operatively arranged in respect to the lips, and a pivot pin by which the two pairs of tongs vare concentrically pivoted and which has threaded engagement with one element of the pairof setting tongs, substantially as described.

5. A saw-set comprising the. combination of a pivot pin, a pair offspring-opened clamping tongs each provided with a clamping lip and with arms spaced apart and eX- tending between the lips/.and the pinand whereof one iscontinued beyond the pin and offset to\bringthe lshanks into substantially the same plane, a pair of settingtongs pivoted to said pin and provided with sets arranged in the space between the-arms and having their shanks outside of land substantially in the same plane with the shanks of the clamping tongs, and springs and abutments interposed between. the shanks of the respective tongs, substantially as'de scribed.
